Well-Known Ports and Their Services

Well-Known Ports and Their Services

Having read the internetworking primers in Chapter 1, “Understanding Communication Protocols,”
and Chapter 3, ‘‘Understanding Communication Mediums,” hopefully you are beginning to think,
speak, and, possibly, act like a hacker, because now it’s time to apply that knowledge and hack your
way to a secure network. We begin this part with an in-depth look at what makes common ports and
their services so vulnerable to hack attacks. Then, in Chapter 5, you will learn about the software,
techniques, and knowledge used by the hackers, crackers, phreaks, and cyberpunks defined in Act I
Intermission.

A Review of Ports

The input/output ports on a computer are the channels through which data is transferred between an
input or output device and the processor. They are also what hackers scan to find open, or
“listening,” and therefore potentially susceptible to an attack. Hacking tools such as port scanners
(discussed in Chapter 5) can, within minutes, easily scan every one of the more than 65,000 ports on
a computer; however, they specifically scrutinize the first 1,024, those identified as the well-known
ports. These first 1,024 ports are reserved for system services; as such, outgoing connections will
have port numbers higher than 1023. This means that all incoming packets that com municate via
ports higher than 1023 are replies to connections initiated by internal requests.
When a port scanner scans computer ports, essentially, it asks one by one if a port is open or closed.
The computer, which doesn’t know any better, automatically sends a response, giving the attacker
the requested information. This can and does go on without anyone ever knowing anything about it.
The next few sections review these well-known ports and the corresponding vulnerable services they
provide. From there we move on to discuss the hacking techniques used to exploit security
weaknesses.

The material in these next sections comprises a discussion of the most vulnerable

ports from the universal well-known list. But because many of these ports and

related services are considered to be safe or free from common penetration attack

(their services may be minimally exploitable), for conciseness we will pass over safer

ports and concentrate on those in real jeopardy.

TCP and UDP Ports

TCP and UDP ports, which are elucidated in RFC793 and RFC768 respectively, name the ends of
logical connections that mandate service conversations on and between systems. Mainly, these lists
specify the port used by the service daemon process as its contact port. The contact port is the
acknowledged “well-known port.”
Recall that a TCP connection is initialized through a three-way handshake, whose purpose is to
synchronize the sequence number and acknowledgment numbers of both sides of the connection,
while exchanging TCP window sizes. This is referred to as a connection-oriented, reliable service.

On the other side of the spectrum, UDP provides a connectionless datagram service that offers
unreliable, best-effort delivery of data. This means that there is no guarantee of datagram arrival or
of the correct sequencing of delivered packets. Tables 4.1 and 4.2 give abbreviated listings,
respectively, of TCP and UDP ports and their services (for complete listings, refer to Appendix C in
the back of this book).

Well-Known Port Vulnerabilities

Though entire books have been written on the specifics of some of the ports and services defined in
this section, for the purposes of this book, the following services are addressed from the perspective
of an attacker, or, more specifically, as part of the “hacker’s strategy.”

Port: 7

Service: echo

Hacker’s Strategy: This port is associated with a module in communications or a signal transmitted

(echoed) back to the sender that is distinct from the original signal. Echoing a message back to the
main computer can help test network connections. The primary message-generation utility executed
is termed PING, which is an acronym for Packet Internet Groper. The crucial issue with port 7’s
echo service pertains to systems that attempt to process oversized packets. One variation of a
susceptible echo overload is performed by send ing a fragmented packet larger than 65,536 bytes in
length, causing the system to process the packet incorrectly, resulting in a potential system halt or
reboot. This problem is commonly referred to as the ‘‘Ping of Death” attack. Another common
deviant to port 7 is known as “Ping Flooding.” It, too, takes advantage of the computer’s
responsiveness, using a continual bombardment of pings or ICMP Echo Requests to overload and
congest system resources and network segments.

Port: 11

Service: systat

Hacker’s Strategy: This service was designed to display the status of a machine’s current operating
processes. Essentially, the daemon associated with this service bestows insight into what types of
software are currently running, and gives an idea of who the users on the target host are.
Port: 15
Service: netstat
Hacker’s Strategy: Similar in operation to port 11, this service was designed to display the
machine’s active network connections and other useful informa tion about the network’s subsystem,
such as protocols, addresses, connected sockets, and MTU sizes. Common output from a standard
Windows system would display what is shown in Figure 4.2.
Figure 4.2 Netstat output from a standard Windows system.
Port: 19
Service: chargen
Hacker’s Strategy: Port 19, and chargen, its corresponding service daemon, seem harmless enough.
The fundamental operation of this service can be easily deduced from its role as a character stream
generator. Unfortunately, this service is vulnerable to a telnet connection that can generate a string of
characters with the output redirected to a telnet connection to, for example, port 53 (domain name
service (DNS)). In this example, the flood of characters causes an access violation fault in the DNS
service, which is then terminated, which, as a result, disrupts name resolution services.
Port: 20, 21
Service: FTP-data, FTP respectively
Hacker’s Strategy: The services inherent to ports 20 and 21 provide operability for the File Transfer
Protocol (FTP). For a file to be stored on or be received from an FTP server, a separate data
77
connection must be utilized simultaneously. This data connection is normally initiated through port
20 FTP-data. In standard operating procedures, the file transfer control terms are mandated through
port 21. This port is commonly known as the control connection, and is basically used for sending
commands and receiving the coupled replies. Attributes associated with FTP include the capability to
copy, change, and delete files and directories. Chapter 5 covers vulnerability exploit techniques and
stealth software that are used to covertly control system files and directories.
Port: 23
Service: telnet
Hacker’s Strategy: The service that corresponds with port 23 is commonly known as the Internet
standard protocol for remote login. Running on top of TCP/IP, telnet acts as a terminal emulator for
remote login sessions. Depending on preconfigured security settings, this daemon can and does
typically allow for some way of controlling accessibility to an operating system. Uploading specific
hacking script entries to certain Telnet variants can cause buffer overflows, and, in some cases,
render administrative or root access. An example includes the TigerBreach Penetrator (illustrated in
Figure 4.3) that is part of TigerSuite, which is included on the CD bundled with this book and is
more fully introduced in Chapter 12.
Port: 25
Service: SMTP
Hacker’s Strategy: The Simple Mail Transfer Protocol (SMTP) is most commonly used by the
Internet to define how email is transferred. SMTP daemons listen for incoming mail on port 25 by
default, and then copy messages into appropriate mailboxes. If a message cannot be delivered, an
error report containing the first part of the undeliverable message is returned to the sender. After
establishing the TCP connection to port 25, the sending machine, operating as the client, waits for
the receiving machine, operating as the server, to send a line of text giving its identity and telling
whether it is prepared to receive mail. Checksums are not generally needed due to TCP’s reliable
byte stream (as covered in previous chapters). When all the email has been exchanged, the
connection is released. The most common vulnerabilities related with SMTP include mail bombing,
mail spamming, and numerous denial of service (DoS) attacks. These exploits are described in detail
later in the book.
78

Port: 43
Service: Whois
Hacker’s Strategy: The Whois service (http://rs.Internic.net/whois.html) is a TCP port 43
transaction-based query/response daemon, running on a few specific central machines. It provides
networkwide directory services to local and/or Internet users. Many sites maintain local Whois
directory servers with information about individuals, departments, and services at that specific
domain. This service is an element in one the core steps of the discovery phase of a security analysis,
and is performed by hackers, crackers, phreaks, and cyberpunks, as well as tiger teams. The most
popular Whois databases can be queried from the InterNIC, as shown in Figure 4.4.
Figure 4.4 The most popular Whois database can be queried.
79
Port: 53
Service: domain
Hacker’s Strategy: A domain name is a character-based handle that identifies one or more IP
addresses. This service exists simply because alphabetic domain names are easier to remember than
IP addresses. The domain name service (DNS) translates these domain names back into their
respective IP addresses. As explained in previous chapters, datagrams that travel through the Internet
use addresses, therefore every time a domain name is specified, a DNS service daemon must
translate the name into the corresponding IP address. Basically, by entering a domain name into a
browser, say, TigerTools.net, a DNS server maps this alphabetic domain name into an IP address,
which is where the user is forwarded to view the Web site. Recently, there has been extensive
investigation into DNS spoofing. Spoofing DNS caching servers give the attacker the means to
forward visitors to some location other than the intended Web site. Another popular attack on DNS
server daemons derives from DoS overflows, rendering the resources inoperable. An illustration of a
standard DNS query is shown in Figure 4.5.
Figure 4.5 Output from a standard DNS query.
Port: 67
Service: bootp
Hacker’s Strategy: The bootp Internet protocol enables a diskless workstation to discover its own
IP address. This process is controlled by the bootp server on the network in response to the
workstation’s hardware or MAC address. The primary weakness of bootp has to do with a kernel
module that is prone to buffer overflow attacks, causing the system to crash. Although most
occurrences have been reported as local or internal attempts, many older systems still in operation
and accessible from the Internet remain vulnerable.
Port: 69
80
Service: tftp
Hacker’s Strategy: Often used to load Internetworking Operating Systems (IOS) into various
routers and switches, port 69 Trivial File Transfer Protocol (tftp) services operate as a less
complicated form of FTP. In a nutshell, tftp is a very simple protocol used to transfer files. tftp is
also designed to fit into read-only memory, and is used during the bootstrap process of diskless
systems. tftp packets have no provision for authentication; because tftp was designed for use during
the bootstrap process, it was impossible to provide a username and password. With these glitches in
numerous variations of daemons, simple techniques have made it possible for anyone on the Internet
to retrieve copies of world-readable files, such as /etc/passwd (password files), for decryption.
Figure 4.6 Output from a successful finger query.
Port: 79
Service: finger
Hacker’s Strategy: When an email account is “fingered,” it returns useful discovery information
about that account. Although the information returned varies from daemon to daemon and account to
account, on some systems, finger reports whether the user is currently in session. Other systems
return information including the user’s full name, address, and/or telephone number. The finger
process is relatively simple: A finger client issues an active open to this port, and sends a one-line
query with login data. The server processes the query, returns the output, and closes the connection.
The output received from port 79 is considered highly sensitive, as it can reveal detailed information
on users. Sample output from the Discovery: finger phase of an analysis is shown in Figure 4.6. The
actual data is masked for user anonymity.
Port: 80
Service: http
Hacker’s Strategy: An acronym for the Hypertext Transfer Protocol, HTTP is the underlying
protocol for the Internet’s World Wide Web. The protocol defines how messages are formatted and
transmitted, and operates as a stateless protocol because each command is executed independently,
without any knowledge of the previous commands. The best example of this daemon in action occurs
when a Web site address (URL) is entered in a browser. Underneath, this actually sends an HTTP
command to a Web server, directing it to serve or transmit the requested Web page to the Web
browser. The primary vulnerability with specific variations of this daemon is the Web page hack. An
81
example from the infamous hacker Web site, www.2600.com/hacked_pages, shows the “hacked”
United States Army home page (see Figure 4.7).
Port: 109, 110
Service: pop2, pop3, respectively
Hacker’s Strategy: The Post Office Protocol (POP) is used to retrieve email from a mail server
daemon. Historically, there are two well-known versions of POP: the first POP2 (from the 1980s)
and the more recent, POP3. The primary difference between these two flavors is that POP2 requires
an SMTP server daemon, whereas POP3 can be used unaccompanied. POP is based on client/server
topology in which email is received and held by the mail server until the client software logs in and
extracts the messages. Most Web browsers have integrated the POP3 protocol in their software
design, such as in Netscape and Microsoft browsers. Glitches in POP design integration have
allowed remote attackers to log in, as well as to direct telnet (via port 110) into these daemons’
operating systems even after the particular POP3 account password has been modified. Another
common vulnerability opens during the Discovery phase of a hacking analysis, by direct telnet to
port 110 of a target mail system, to reveal critical information, as shown in Figure 4.8.
Port: 111, 135
Service: portmap, loc-serv, respectively
Hacker’s Strategy: The portmap daemon converts RPC program numbers into port numbers. When
an RPC server starts up, it registers with the portmap daemon. The server tells the daemon to which
port number it is listening and which RPC program numbers it serves. Therefore, the portmap
daemon knows the location of every registered port on the host, as well as which programs are
available on each of these ports. Loc-serv is NT’s RPC service. Without filtering portmap, if an
intruder uses specific parameters and provides the address of the client, he or she will get its NIS
domain name back. Basically, if an attacker knows the NIS domain name, it may be possible to get a
copy of the password file.
82

Figure 4.8 Telnetting can reveal critical system discovery information.
83
Figure 4.9 Sample output from the netstat -a command.
Port: 137, 138, 139
Service: nbname, nbdatagram, nbsession, respectively
Hacker’s Strategy: Port 137 nbname is used as an alternative name resolution to DNS, and is
sometimes called WINS or the NetBIOS name service. Nodes running the NetBIOS protocol over
TCP/IP use UDP packets sent from and to UDP port 137 for name resolution. The vulnerability of
this protocol is attributed to its lack of authentication. Any machine can respond to broadcast queries
for any name for which it sees queries, even spoofing, by beating legitimate name holders to the
response. Basically, nbname is used for broadcast resolution, nbdatagram interacts with similar
broadcast discovery of other NBT information, and nbsession is where all the point-to-point
communication occurs. A sample netstat –a command execution on a Windows station (see Figure
4.9) would confirm these activities and reveal potential Trojan infection as well.
Port: 144
Service: news
Hacker’s Strategy: Port 144 is the Network-extensible Window System (news), which, in essence,
is an old PostScript-based window system developed by Sun Microsystems. It’s a multithreaded
PostScript interpreter with extensions for drawing on the screen and handling input events, including
an object-oriented programming element. As there are limitations in the development of a standard
windows system for UNIX, the word from the Under ground indicates that hackers are currently
working on exploiting fundamental flaws of this service.
Port: 161, 162
Service: snmp, snmp-trap, respectively
Hacker’s Strategy: In a nutshell, the Simple Network Management Protocol (snmp) directs network
device management and monitoring. snmp operation consists of messages, called protocol data units
(PDUs), that are sent to different parts of a network. snmp devices are called agents. These
components store information about themselves in management information bases (MIBs) and return
this data to the snmp requesters. UDP port 162 is specified as the port notification receivers should
listen to for snmp notification messages. For all intents and purposes, this port is used to send and
receive snmp event reports. The interactive communication governed by these ports makes them
juicy targets for probing and reconfiguration.
Port: 512
84
Service: exec
Hacker’s Strategy: Port 512 exec is used by rexec() for remote process execution. When this port is
active, or listening, more often than not the remote execution server is configured to start
automatically. As a rule, this suggests that X-Windows is currently running. Without appropriate
protection, window displays can be captured or watched, and user keystrokes can be stolen and
programs remotely executed. As a side note, if the target is running this service daemon, and accepts
telnets to port 6000, the ingredients are present for a DoS attack, with intent to freeze the system.
Port: 513, 514
Service: login, shell, respectively
Hacker’s Strategy: These ports are considered “privileged,” and as such have become a target for
address spoofing attacks on numerous UNIX flavors. Port 514 is also used by rsh, acting as an
interactive shell without any logging. Together, these services substantiate the presence of an active
X-Windows daemon, as just described. Using traditional methods, a simple telnet could verify
connection establishment, as in the attempt shown in Figure 4.10. The actual data is masked for
target anonymity.
Figure 4.10 Successful verification of open ports with telnet.
Port: 514
Service: syslog
Hacker’s Strategy: As part of the internal logging system, port 514 (remote accessibility through
front-end protection barriers) is an open invitation to various types of DoS attacks. An effortless
UDP scanning module could validate the potential vulnerability of this port.
Port: 517, 518
Service: talk, ntalk, respectively
Hacker’s Strategy: Talk daemons are interactive communication programs that abide to both the
old and new talk protocols (ports 517 and 518) that support real-time text conversations with another
UNIX station. The daemons typically consist of a talk client and server, and for all practical
purposes, can be active together on the same system. In most cases, new talk daemons that initiate
from port 518 are not backward-compatible with the older versions. Although this seems harmless,
many times it’s not. Aside from the obvious—knowing that this connection establishment sets up a
TCP connection via random ports—exposes these services to a number of remote attacks.
Port: 520
Service: route
85
Hacker’s Strategy: A routing process, termed dynamic routing occurs when routers talk to adjacent
or neighboring routers, informing one another of which networks each router currently is acquainted
with. These routers communicate using a routing protocol whose service derives from a routing
daemon. Depending on the protocol, updates passed back and forth from router to router are initiated
from specific ports. Probably the most popular routing protocol, Routing Information Protocol (RIP),
communicates from UDP port 520. Many proprietary routing daemons have inherited
communications from this port as well. To aid in target discovery, trickling critical topology
information can be easily captured with virtually any sniffer.
Port: 540
Service: uucp
Hacker’s Strategy: UNIX-to-UNIX Copy Protocol (UUCP) involves a suite of UNIX programs
used for transferring files between different UNIX systems, but more importantly, for transmitting
commands to be executed on another system. Although UUCP has been superseded by other
protocols, such as FTP and SMTP, many systems still allocate active UUCP services in day-to-day
system management. In numerous UNIX flavors of various service daemons, vulnerabilities exist
that allow controlled users to upgrade UUCP privileges.
Port: 543, 544, 750
Service: klogin, kshell, kerberos
Hacker’s Strategy: The services initiated by these ports represent an authentication system called
Kerberos. The principal idea behind this service pertains to enabling two parties to exchange private
information across an open or insecure network path. Essentially, this method works by assigning
unique keys or tickets to each user. The ticket is the n embedded in messages for identification and
authentication. Without the necessary filtration techniques throughout the network span, these ports
are vulnerable to several remote attacks, including buffer overflows, spoofs, masked sessions, and
ticket hijacking.
Unidentified Ports and Services
Penetration hacking programs are typically designed to deliberately integrate a backdoor, or hole, in
the security of a system. Although the intentions of these service daemons are not always menacing,
attackers can and do manipulate these programs for malicious purposes. The software outlined in this
section is classified into three interrelated categories: viruses, worms, and Trojan horses. They are
defined briefly in turn here and discussed more fully later in the book.
· A virus is a computer program that makes copies of itself by using, and therefore requiring, a
host program.
· A worm does not require a host, as it is self-preserved. The worm compiles and distributes
complete copies of itself upon infection at some predetermined high rate.
· A Trojan horse, or just Trojan, is a program that contains destructive code that appears as a
normal, useful program, such as a network utility.
Most of the daemons described in this section are available on this book’s CD or
through the Tiger Tools Repository of underground links and resources, also found
on the CD.
86
The following ports and connected services, typically unnoticed by target victims, are most
commonly implemented during penetration hack attacks. Let’s explore these penetrators by active
port, service or software daemon, and hacker implementation strategy:
Port: 21, 5400-5402
Service: Back Construction, Blade Runner, Fore, FTP Trojan, Invisible FTP, Larva, WebEx,
WinCrash
Hacker’s Strategy: These programs (illustrated in Figure 4.11) share port 21, and typically model
malicious variations of the FTP, primarily to enable unseen file upload and download functionality.
Some of these programs include both client and server modules, and most associate themselves with
particular Registry keys. For example, common variations of Blade Runner install under:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
Port: 23
Service: Tiny Telnet Server (TTS)
Hacker’s Strategy: TTS is a terminal emulation program that runs on an infected system in stealth
mode. The daemon accepts standard telnet connectivity, thus allowing command execution, as if the
command had been entered directly on the station itself. The associated command entries derive
from privileged or administrative accessibility. The program is installed with migration to the
following file: c:\windows\Windll.exe. The current associated Re gistry key can be found under:
